Objectives: Determine affect of change to aft balance and progressively increasing weights to establish maximum weight
|
|||
Check |
Action |
||
PRE-FLIGHT |
|||
Carefully weigh and secure ballast |
|||
Compute & record new weight & balance |
|||
DEPARTURE |
|||
Note: 10% flaps can help lift tail as aft weight is added. |
|||
Climb out at 110 MPH |
|||
Climb to 6000 MSL and level off |
|||
Record climb performance: FPM = ____ |
|||
CRUISE |
|||
Limit prop RPM to 2300 |
|||
Check engine gauges especially CHT and Oil Temp |
|||
Trim hands off level flight |
|||
SLOW FLIGHT & STALLS |
|||
360 turns, slow flight & power off stall w/ no flaps, 1/2 flaps, full flaps, recover |
|||
Execute power-on stalls @ 2200 RPM |
NOTES
Salt bags work well as ballast. Make sure they are securely belted in.

STABILITY & CONTROL CHECKS |
|
Longitudinal Stability: Record Airspeed @ 2200 RPM (A) |
|
Pull to reduce to A-10%=B, require continued pull for B? Yes=Positive LS |
|
Do push test |
|
Lateral/Directional Control Stability: Sideslip |
|
Release Aileron (keep rudder), Do wings level? |
|
Static Directional Stability: Yaw w/ level wings, release rudder. Return to no yaw? |
|
Spiral Stability: Bank 15 deg., release. Return to level? |
|
ACCELERATED STALLS |
|
15 Degree bank, slow until stalls: Repeat w/ 30, 45, 60 |
|
DESCENT RATE |
|
Descend @ 90 MPH, record rate. Record loss of elevation w/ 90, 180, 360 degree turns |
|
POST FLIGHT |
|
Prepare corrective action list |
|
Record fuel and oil consumption |
NOTES
These weight & balance tests were specifically designed for RV-4 N9X. Other aircraft will require uniquely different weight & balance configurations. The objective is to incrementally test the affect of increased weight and aft weight on the aircraft handling. DO NOT EXCEED GROSS WEIGHT. STAY WITHING THE FORE/AFT CG LIMITS.
